ABT / IEGC CLAUSES
Capability Declaration during Peak hours:
ABT
Schedule-I
Para 3 (iii)
(Page iii)
While making or revising their
declaration of capability, the
generator shall ensure that their
declared capability during peak
hours is not less than that during
other hours.
ABT / IEGC CLAUSES
Generation beyond DC
IEGC
Chapter-6,
Para 6.2(g)
(Page 6.2)
The generating units operating
at about 100% of their MCR
shall be capable of (and shall
not be prevented from ) going at
least up to 105% of their MCR
when frequency falls suddenly.
ABT / IEGC CLAUSES
Generation beyond DC
ABT
Schedule-I
Para 4(ii)
(Page v)
SOC for Thermal Stations shall
be the DC, with all before-thefact revisions / updating. The
declared capacity shall not
exceed the installed capacity.
ABT / IEGC CLAUSES
Generation beyond DC
In case it is observed that the
declaration of its capability by the
generator is on lower side and the
ABT
Schedule-1 actual generation is more than DC,
Para-6
then UI charges due to the generator
(Page vi) on account of such extra generation
shall be reduced to zero and the
amount shall be credited towards UI
account of beneficiaries in the ratio of
their capacity share in the station.
ABT / IEGC CLAUSES
Separate Schedules for Gas/Liquid
ABT
Schedule-I
Para 4
(Note 1)
(Page v)
In case of gas turbine / combined
cycle stations, the generator shall
give DC for units / modules on
gas fuel and DC for units /
modules
on
liquid
fuel
separately.
ABT / IEGC CLAUSES
Revision of Schedules initiated by RLDCs
IEGC
Chapter-7
Para 7.4.9
(Page-7.3)
RLDC may direct the SLDCs/
ISGS to increase/decrease their
drawal / generation in case of
contingencies e.g. overloading
of
lines
/
transformers,
abnormal voltages, threat to
system security.
ABT / IEGC CLAUSES
Revision of Schedules initiated by RLDCs
ABT
Schedule-1
Para-3(xv)
RLDC may revise the schedule
in the interest of better system
operation w.e.f 4th time block.
ABT / IEGC CLAUSES
Revision of schedules at the request of Generators/States
Revision of declared capability by
generator
(s)
and
requisition
by
beneficiary(ies) for the remaining period of
ABT
the day will also
be permitted with
Schedule-1
advance notice.
Revised schedules /
Para (xiv)
declared capability in such cases shall
(Page (iv)
become effective from the 6th time block,
counting the time block in which the
request for revision has been received in
RLDC to be the first one.
ABT / IEGC CLAUSES
Ramping-up/Ramping-down
While finalising the above daily
generation schedules for the ISGS,
IEGC
RLDC shall ensure that the same are
Chapter-7 operationally reasonable, particularly
Para 7.5.7
in terms of ramping-up/ramping(Page 7.5)
down rates and the ratio between
minimum and maximum generation
levels.
ABT / IEGC CLAUSES
Integrated Grid Operations and Economey
The Regional Load Despatch Centre
may give such directions and exercise
such supervision and control as may
IEGC
Chapter-2 be required for ensuring integrated
Para 2.2. (2) grid operations and for achieving the
(Page 2-1)
maximum economy and efficiency in
the operation of the power system in
the region under its control
ABT / IEGC CLAUSES

IEGC
Chapter-6
Para 6.1 (a)
(Page 6-1)
The primary objective of integrated
operation of the Regional grids is to enhance
the overall operational economy and
reliability of the entire electric power
network spread over the geographical area of
the interconnected States.
Participant
utilities shall co-operate with each other and
adopt Good Utility Practice at all times for
satisfactory and beneficial operation of the
Regional grid.

Chapter 2
Para2.6(1)
(Page 2-4)
Subject to the provisions of subsection 55(3) of the Act, State Load
Despatch Centre in a State may give
such directions and exercise such
supervision and control as may be
required for ensuring the integrated
grid operations and for achieving the
maximum economy and efficiency in
the operation of the power system in
that State.
ABT / IEGC CLAUSES
Integrated Grid Operations and Economey
The system of each State shall be
treated and operated as a notional
(flexible) control area.
The
IEGC
Chapter-7 summation of scheduled drawal from
Para 7.4 (2) ISGS and any bilateral inter-change
(Page 7-2) shall provide the drawal schedule of
each State, and this shall be
determined in advance on daily
basis.
ABT / IEGC CLAUSES
Integrated Grid Operations and Economey
The Regional grids shall be operated as loose power
pools in which the States shall have full operational
autonomy, and SLDCs shall have the total
responsibility fori) scheduling / despatching their own generation
IEGC
Chapter-7 (including the generation of their captive licensees),
Para 7.4 (1)
(Page 7-1) (ii) regulating the demand of their customers,
(iii) scheduling their drawal from the ISGS (within
their shares in the respective plant’s capability),
(iv) arranging any bilateral interchanges, and
(v) regulating their net drawal from the regional grid
as per agreed guidelines.

Para 3 (vi)

Based on the requisitions given by
the beneficiaries and taking into
account technical limitations on
varying the generation and also
taking into account transmission
system constraints, if any, RLDC
shall prepare the economically
optimal generation schedules.
